If it's the same battery, the answer is NO.

Just to get an idea what your doing.

The battery that the inverter is connected to is different to the one you want charged, or is it the same battery.

No he will go backwards. The inverter and charger will use more than what's put back in.

HI Box

You have it right going in circles with ever decreasing battery capacity
In fact, every full cycle would loose around 10<15% of battery capacity due to energy lost in the inverter, charger & batteries

This will give you some idea how you will lose power.

When you turn on the inverter it will draw power say 2amps (example only) them if the charger is producing 20 amps it would draw more than the 20 amps, and the charger only puts back 20 amps and hope the battery will accept it, leaves you short by at least 2 amps, but would be more. The tec sav people can give you accurate figures.


If it did work I would have no need for solar panels or generator. Turn my home to 12 volt and never have a power bill again.

Not so much a mobius loop as perpetual motion.

I checked the calender. It ain't 1st April.

So could I ask. Is your friend part of The Chaser team?

Failing that, and assuming for a moment the question is on the up an up.

What exactly is the end game here? What is the object of all this?

Cheers
